Awais Ahmad, Mudassar Ahmad, Muhammad Asif Habib, Shahzad Sarwar, more

The Journal of Supercomputing > 2019 > 75 > 4 > 2269-2288

The main challenge in database-as-a-service is the security and privacy of data because service providers are not usually considered as trustworthy. So, the data must be encrypted before storing into the database. Another challenge arises that the performance is degraded on the deployment of encryption algorithm on runtime. Furthermore, the connectivity through the Internet adds more delay. To tackle...
